Houston, Texas — After a week marked by heavy rainfall, thunderstorms, and localized flooding concerns, Southeast Texas is preparing for a much different weather pattern as a summer heat dome builds across the state.
Forecasters say Houston will experience warmer temperatures, higher humidity, and increasingly uncomfortable conditions throughout the week as the first official days of summer arrive.
The shift means residents will trade umbrellas for air conditioning as heat index values climb into triple digits across much of the region.
Heat Dome Set to Take Hold Across Texas
Weather experts say a strengthening heat dome over West Texas will expand its influence across large portions of the state during the week.
The weather pattern is expected to suppress widespread rainfall while allowing temperatures to steadily rise.
Houston residents can expect morning temperatures to begin in the mid-to-upper 70s, with afternoon highs reaching the low to mid-90s on most days.
While those temperatures may not seem extreme by Texas standards, the combination of heat and humidity will make conditions feel significantly hotter.
Forecasters expect heat index values to range between 100 and 105 degrees during the afternoons, with some locations potentially reaching 108 degrees or higher later in the week.
Heat Advisories Could Become Necessary
The elevated humidity levels will play a major role in how hot it feels outdoors.
Meteorologists warn that prolonged exposure to the heat could increase the risk of heat-related illnesses, especially for those working or exercising outside during peak afternoon hours.
If heat index values exceed established thresholds, portions of Southeast Texas could be placed under Heat Advisories.
Residents are encouraged to stay hydrated, limit strenuous outdoor activities during the hottest part of the day, and check on vulnerable family members and neighbors.
The return of persistent summer heat is a reminder that the region is now entering its hottest stretch of the year.
Breezy Conditions Continue Early in the Week
Monday is expected to feature a warm and somewhat humid start, with temperatures already sitting in the upper 70s during the morning hours.
A few brief showers may develop as the Gulf breeze moves inland, but widespread rainfall is not anticipated.
Southerly winds around 20 mph will create breezy conditions throughout the day, while increasing sunshine helps temperatures climb into the lower 90s.
The combination of sunshine, humidity, and warm winds will contribute to the muggy feel many residents will notice throughout the week.
Houston Just Experienced an Exceptionally Wet Week
The heat arrives after one of the wetter periods of the month across the Houston area.
Rainfall estimates and local gauges indicate that many neighborhoods in Houston and Harris County received between 3 and 7 inches of rain over the past week.
Some communities recorded even higher amounts, with isolated locations receiving more than 9 inches of rainfall.
The heaviest totals were reported farther south in portions of Brazoria and Galveston counties. Near Seabrook, rainfall totals exceeded 12 inches, making it one of the wettest areas in the region.
Heavy Rain Targets Oklahoma, Arkansas and Tennessee as Summer Begins With Flood Threat
June Rainfall Running Well Above Normal
Houston’s official rainfall total for June is approaching 8 inches, which is approximately 4 inches above normal for this point in the month.
The recent storms have helped replenish soil moisture and water supplies, but the upcoming stretch of heat will likely increase evaporation rates and outdoor water usage.
With the first official week of summer now underway, forecasters expect the dominant weather story to shift from heavy rain to prolonged heat and humidity.
Residents should prepare for several days of steamy conditions as Southeast Texas settles into a more typical summer weather pattern.
